You can control the jammer for one or more frequencies

Today's cell phone signals are available in many places. All electrical devices are surrounded by them. When the mobile phone is not in use, the effects of other electrical devices are small. If there is no mobile phone, there is no data communication between the mobile phone and the base station. It won't change the sudden signal. This is a relatively stable electromagnetic field. This static electricity hardly disturbs electronic devices. When using cell phones, the data communication between the cell phone and the base station results in a sudden alternating signal that creates a dynamic electromagnetic field. Dynamic electromagnetic signals can affect the failure of electrical devices. This is the importance of mobile cell phone jammer at gas stations.

Taking the university entrance exam is an important part of this city. To prevent canned food from taking the university entrance exam, we will introduce mobile jammers in the university entrance exam room. Cell phone jammers can interfere with 3G cellular signals. During the civil service examination, fraud was reprinted in newspapers. Reports of fraudulent activity on 3G cell phones are not uncommon. This means that you are using a signal jammer for a 3G phone. Some cell phone jammers increase their 4G signal jamming capabilities. Support college entrance exam to tackle high tech scams in various local exams. To reinforce our response to fraudulent activity in the university entrance exam, we installed cell phone shielding during the university entrance exam.

Handheld Multiband Powerful GSM 3G GPS WIFI Bluetooth Wireless Video Jammer

Cell phone signals are harmful to the human body. Is the cell phone signal harmful to the human body or the cell phone? Make sure that the signal interferer on the cellphone has a very weak electromagnetic signal. Please rest assured that the test data shows that the signal strength is not harmful to the human body. At the same time, the cellphone's signal interferer only shields the cellphone's forward signal so that the WiFi jammer cellphone cannot connect to the base station and the cellphone itself is not damaged. Is there a difference between cell phone signal distance and outdoor gear? The effective distance of a cell phone signal jammer (30-40 meters) is usually related to the indoor distance.

In open outdoor areas, the effective range of the protective cover can reach hundreds of meters. Regardless of whether the GPS jammer is located indoors or outdoors, it should be noted that the effective length of the shielding and the distance to the base station depend on the general environmental conditions such as the installation location. Therefore, this factor must be carefully considered when using a signal interferer in a mobile phone in order to avoid blocking the blind spots, thereby impairing the shielding effect.
